Description: In Git, ‘HEAD’ is a pointer that indicates the current branch the user is on. It is a fundamental concept in version control systems, as it allows developers to know at what point in the project’s history they are working. ‘HEAD’ typically points to the latest commit in the active branch, meaning any changes made will be recorded from that point. Additionally, ‘HEAD’ can be used to navigate between different branches and commits, facilitating version management and collaborative work. When a branch change occurs, ‘HEAD’ automatically updates to reflect the new location in the commit tree. This pointer is essential for understanding how version control systems handle change history and allows users to perform operations like ‘checkout’ and ‘reset’, which are crucial for code manipulation and version management. In summary, ‘HEAD’ is a key component that helps developers maintain a clear track of their work and effectively manage software development in collaborative environments.
